These common blue LEDs (
5mm round 12V and
30cm flexible 12V) are soldered into the lock switch illumination on the front doors. There's a shaped hole in the door handle for a factory LED, but these are just loose in those locations. There are also factory strips that snap into the grooves above the door pockets, but the strips are loose in there, too. To remove the door panels, the LEDs simply pull back out - no connectors or adhesives are used.
